v claims.
This invention relates to` bed springs and its
principal objects are to provide an improved bed
spring structure which will afford a desirable
degree of resiliency or softness but which will be
5 substantially free from` objectionable sidesway;
to provide a structure in which certain relatively
moving parts are interconnected to maintain a
predetermined relation, the connection being ef
fected in a manner to preventI the production of
m‘l'scratching or squeaking noises and to prevent
scratching of one part by the other as an incident
to relative movement between such parts; to pro
vide an improved structure which may be com
mercially produced on a large scale and econom
15~ ically at a low cost, and in general, it is they object
of this invention to provide an improved bed
spring.

Other axially vertical coil springs designated
I6 are also supported by the spring supports I2 5%
and the springs I6 are arranged in rows which
extend both longitudinally and Vtransversely of
the bedspring, and hence in rows which extend
transversely of each other. The rows of inner
springs I6 are also arranged in alignment with l0
oppositely -disposed border springs which, as above
stated, are anchored to the top border frame.
The axially vertical springs preferably have
certain coils intermediate their upper and lower
ends connected by tie wires or the like, such as 16
indicated at Il, and these connections may be of
any conventional form suitably attached tothe
respective spring coils. Said ties Il may extend ‘

`
Referring now to the drawing, the bedspring
herein illustrated includes an upper border frame
I0 preferably formed of angle iron and a lower
35 border frame II also preferably formed of angle
iron. The lower border frame II is preferably
arranged with its ilanges disposed horizontally
and vertically, the vertical flange extending from
the inner edge of the horizontal iiange. Spring
40‘ supports such as indicated at I2 are secured at
their ends to oppositely disposed lower border
frame portions, substantially as illustrated in Fig.
2, and axially vertical coil springs are supported
on said springsupports I2 in the more or less
45 conventional manner.
The outermost or border springs designated I3
have their top coils suitably anchored to the up
per border frame I0. In thisiinstance, the upper
border frame IIJ is preferably arranged with its
60 ñanges arranged horizontally and vertically, the
vertical ñange depending from the outer edge of
the horizontal flange. Thelsaid top coils of the
border springs I3 may convenientlybe connected
to said‘upper border frame by providing such top
55 i coils with ears or loops I4 which extend under
The top coils of the inner springs I6 and the
border springs I3 are preferably connected by
means of pairs of crossed helicals designated I8,
said crossed helicals being preferably interlaced
and provided at their ends with hooks for en- 25‘
gaging the respective top coils. Said crossed heli
cals serve to resiliently connect the upper ends
of the springs so as to yieldingly maintain the
same‘in Substantially ñxed relation and they also
serve to provide support for bedding intermediate 30 C
the top coils of thesprings. `
To more effectively support the inner springs
I6 against lateral movement or sidesway and to
provide additional supporting area for bedding,
there are provided a plurality of thin, nexible, 35V`
sheet metal straps, some of which extend trans
versely of the bed spring and others of which ex
tend longitudinally of the bedspring. All of the
straps, however, overlie rows of springs interme
diate` oppositely disposed border springs.

In this instance, straps extending transversely
of the bedspring are designated I9 and straps ex
tending longitudinally of the bedspring are desig
nated 2U. Each of the straps I9 and 29 ter
minates short of the oppositely disposed border 45
springs with which it is aligned, and each strap
has its ends resiliently or yieldingly connected to
the top coil‘of such aligned border springs by
means of a, helical spring 2I.
The springs ZI are 50
provided with hooked ends adapted to hook over
the respective top coils and to engage in suitable
apertures provided in the ends of the respective
straps. It will be evident that the straps I9 and
20 will yieldingly resist lateral Ymovement by rea- 55

The longitudinally extending straps 20 are
preferably secured to some of the top coils which
they overlie. Such connections may be formed
increased by the described structure.
by means of wire loops designated 22 which ex
tend through suitably spaced apertures provided
in the straps 20 and around the adjacent portion
of the top coil of a spring I6. The straps may
10 be connected to each top coil, but such connec
tions to three or four springs in the row give ex
cellent results.
The transversely extending straps I9 may be

As indicated in Fig. 3, the length of the eye is
preferably nearly twice the width of the strap
which extends through the eye, so that limited
lateral movement of the strap in the eye is per
mitted. It will, however, be evident that the ex~
tent of such movement may be enlarged or di
minished as desired. The straps 20 which con
trol the limited lateral movement of the straps l0
l I9 may be referred to as spacer straps to distin
guish them from the straps I 9.
Y The described structure obviously involves no

preferably slidably connected to the longitudi
nally extending straps 29, so as to maintain the
straps I9 and 2U in substantially coplanar rela~
tion and to prevent relative movement from and
20 toward each other which might tend to-produce
objectionable noises.
,
In this instance such sliding connection be
tween the straps I9 and 20 is effected by pressing
relatively narrow, elongated . portions
of the
straps 20 to form eyes through which the straps
I9 may pass. As best shown in Figs. 3 and 4,
the eyes are formed by longitudinally slitting the
straps 20 at transversely spaced points designated
23 intermediate thewidth of the strap and press
ing the intermediate narrow portion designated
24 from the plane of the strap into relatively
spaced relation thereto.
'I‘he narrow portion 24 and the remaining rela
Ytively narrow portions designated 25 and 26 of
35 `the strap 20 on opposite sides of the intermediate
portion 24, are preferably treated so as to prevent
scratching of the transversely extending member
I9 incident to its movement in the eye.
In this
instance such treatment consists in so shaping
40 said narrow portion transversely as to provide
"rounded or smoothed surfaces free from sharp
edges for contacting the opposite sides of the
strap I9. As clearly shown in Fig. fl, the inter
mediate portion 24 may be arranged transversely
45 so that its centrally located portion is spaced
"from the plane of its side edges 21 which may be
quite sharp’. The oppositely, disppsed narrow
portions 25 and 26 may be provided with the
lpunch-press operation and the parts may be
readily so formed in the punching as to produce
as loose or tight connection between the straps
as may be desired. Preferably the connection is
such that the straps may freely slide transversely 20
of `each other, but may not move toward and
from each other so as to avoid the possible pro
duction of noise which might occur by frequent
disengagement and re-engagement of the straps.
Changes in the described structure may be
made without departing from the spirit of the
invention, the scope 0f which should be deter
mined by reference to the following claims, the
same being construed as broadly as possible con
sistent with the state of the art.
I claim:
`
1. A bedspring having a plurality of axially ver
tical coil springs arranged in transversely ex
tending rows, and provided with thin, flexible, me
tallic straps supported so as to respectively over
lie said spring rows and extending transversely
of each other, one of said straps having a longi
tudinally extending, narrow elongated portion
intermediate its width, severed along its sides
from the strap but having its ends integrally con 40.
nected to the strap, said narrow elongated por
tion being pressed from the strap into spaced re
lation thereto to form an eye, a-transversely ex
tending strap being slidably disposed in said eye
and thereby maintained in substantially coplanar
relation to the other strap, the opposed inner
pressed elongated, transversely rounded portions

gaging the transversely extending strap member
disposed therein.
said narrow portions.
By the described arrange
ment, the slidably connected strap portions are
provided with non-scratching bearing surfaces.
55.; The last described feature is particularly ad
vantageous, especially in respect of the protec
tion afforded the top surface of the straps I9
which are plainly visible to a prospective pur
Chaser of a bedspring. In some instances, the
60 ¿straps I9 and 29 may have polished surfaces and
in some instances they may be coated with lac
quer or other material of pleasing color. As a
prac-tical matter, the manufacturer of bedsprings
finds it convenient to purchase the strap material
¿from the producer thereof polished or colored as
desired. In the assembling of such polished or
colored straps, especially in the sliding connec
tion described, the provision of the described
non-scratching arrangement is especially advan
70 l¿tageous in that the bedspring manufacturer is en
abled to go about the work of assembling said
parts without the exercise of extreme caution to
prevent scratching of the parts as an incident to
the assembling operation. Hence, the percent
